Altus VTOL conversion kit

Required additional components:

• 2× DS-S007M 21g servo (or similar, dimensions shown in the image)

• 2× 623zz bearings

• 10× M3 × 20 mm screws

• 12× M1.7 × 4 mm screws (similar-sized self-tapping screws can be used)

• 2× M3 × 6 mm screws

• 8× M3 nuts

• 8× washers

• 4× 3 × 8 mm self-tapping screws

Instructions:

Print 2× "Front-arm-A", "Front-arm-B", "Front-arm-motor", and "Servo-w-bearing". Mirror the second set. Some parts require supports.

Attach the motor to the printed part using screws 6–8 mm long.

Melt or carve a channel for the motor wires in the "Front-arm-A" part (bearing side).

Replace the servo cover and insert the bearing in its place.

Use an "X"-shaped servo horn and cut off two arms to form a "V" shape.

Insert the servo and screw it into the printed part.

You can lightly glue the M3 nuts into their designated slots in the arms—be careful not to clog the threads.

Instead of using the "Front-arm-lock" (which requires additional screws), you can glue parts A and B together after installing the servo.

Remove the inserts from the original motor mount (gondola) and attach the arms to it using screws. You can also reinforce it with double-sided tape.

The "Front-arm-plate" washer/spacer is optional—you don’t have to print it.

Route the motor wires through the printed part and attach the servo horn to both the servo and the print using M1.7 screws. Insert the M3 × 6 mm screw through the bearing.

Shots from the flight at the beginning of the film:

I recommend 2205 motors or slightly larger, with 6045 or 7042 2-blade propellers.
Flying weight about 1050g with HD fpv and 4s 5000mAh li-ion.
Current while hovering 12-15A.
Multirotor flight time approximately 15 minutes, combined flight time not tested yet...  :)
